We're only going to see more and more of this, as regular bidders use it as a bidding strategy to create the appearance of shilling.
I hate it, wish Ebay would do away with serial retractors or start giving warnings out when they reach a certain threshold at least...............like 3......in a year or so.
What sucks now, is I can't even block that guy with 5000 retractions (though it looks like he's a straight up shiller), because Ebay has blocked his ID from view.
So Ebay won't protect me from him (as a buyer OR a seller), and I can't protect myself from him either until he actually affects me.
